Abstract
A wearable device may include a motor, a motor driver circuit, a frame connected to the motor, the frame to be worn on the body of the user to support the body, a processor configured to generate a control signal to control an electrical connection in the motor driver circuit, and a sensor configured to sense a body motion of the user. The processor is further configured to provide an exercise load through the frame according to a speed of the sensed body motion by controlling, based on the speed of the body motion, a changing ratio per time between a first control state in which the electrical connection in the motor driver circuit is a closed loop and a second control state in which the electrical connection in the motor driver circuit is an open loop.
Claims19
A wearable device configured to provide a user with an exercise load while being worn on a body of the user, the wearable device comprising:
- a frame configured to be worn on the body of the user to support the body;
- a motor configured to attach to the frame;
- a motor driver circuit connected to the motor;
- a sensor configured to sense a body motion of the user;
- and
- a processor configured to generate a control signal to control an electrical connection the motor driver circuit to provide the exercise load through the frame according to a speed of the body motion by controlling, based on the speed of the body motion, a changing ratio per time between a first control state and a second control state, the first control state being a state in which the electrical connection in the motor driver circuit is a closed loop and the second control state being a state in which the electrical connection in the motor driver circuit is an open loop.
A method of operating a wearable device configured to provide a user with an exercise load while being worn on a body of the user, the wearable device including a frame configured to be worn on the body of the user, and a motor configured to attach to the frame, the method comprising:
- sensing, via a sensor, a body motion of the user;
- and
- generating a control signal to control an electrical connection in a motor driver circuit of the wearable device based on a speed of the body motion to provide the exercise load through the frame according to the speed of the body motion by controlling, based on the control signal, a changing ratio per time between a first control state and a second control state, the first control state being a state in which the electrical connection in the motor driver circuit is a closed loop and the second control state being a state in which the electrical connection in the motor driver circuit is an open loop.
